title: IgD kappa plasma cell dyscrasias: extraosseous manifestations including isolated leptomeningitis.
abstract: IgD kappa plasma cell Dyscrasias are rare. Two cases with unusual presentations and courses area described. One of these patients had myelomatous pleural effusions, and subsequently experienced myelomatous leptomeningitis. The significance of this combination is discussed and the literature reviewed. The value of immunofluorescent techniques in identifying plasma cells in the cerebrospinal fluid and pleural fluid is emphasized.
